Tin dioxide nanostructured thin films properties obtained by the photoluminescent methods are reported.As a result of the researches fulfilled the luminescence in the visible region of 577 nm and 642 nm was established which is not yet reported in the literature. The luminescent mechanism connected with the system of centers typical for nanostructured objects are analyzed. The radiation spectra types changes, caused by the thermal treatment of a nanoscale tin dioxide films were noticed, which may be connected with structural transformations. These transformations seems caused the luminescent mechanism change from the intercenters' type to the recombinational one.
